Key Lime Fudge
It’s not a typical fudge flavor at all. In fact, it’s not even chocolate! There’s white chocolate in the recipe, but we all know that’s not really chocolate. The white chocolate acts as a vessel for containing an amazing sweet lime flavor. If you’re a lime lover, then this fudge recipe is for you.
Key Lime Fudge is a nice fudge to make during the holiday season to place on holiday treat platters or for gifting to friends and neighbors. I think people like to see and sample something that is a little different. This is definitely different than your typical fudge recipe.
What are Key Limes?
Key limes get their name from the Florida Keys, where Key Lime Pies are abundant! They have a stronger scent and a thinner rind than the typical lime. The flavor is more tart and bitter.
Have you ever picked up a bag of key limes? They’re awfully cute. They’re tiny little things. You’ve gotta squeeze the heck out of them to get every bit of their juice, but it’s all worth it.
These limes present themselves nicely in sweet treats (like key lime pie!) since the sugar balances out that tart flavor and highlights the unique flavor of the key lime. I love them! And if you love them too, then you must try my Key Lime Pie Ice Cream!
How do you make Key Lime Fudge?
Evaporated milk, sugar and salt are heated together in a saucepan and boiled for 8 minutes. Once that mixture has boiled for several minutes, it’ll be piping hot. At that point, you’ll pull the pan off the stove and stir in marshmallows, white chocolate, lime zest and lime juice. All should melt nicely, and then you’ll scrape the fudge mixture into a pan to cool. Once cooled, it’s ready to be cut into squares and eaten!
Can you use regular limes to make Key Lime Fudge?
You can most certainly use regular limes for this fudge. They might give the fudge a slightly sweeter flavor, but all will still be good. Don’t skimp on the lime zest in this recipe since it gives the fudge a fabulous green tint, and it adds a good amount of lime flavor to the recipe too. Oh, and if you want to make the whole process of making this Key Lime Fudge a zillion times easier, then just buy Nellie & Joe’s Key Lime Juice in your market’s juice section. It’ll work just fine for this recipe!
So if you’re wishing for a little “spring” in your life and it hasn’t quite arrived yet, treat yourself to some Key Lime Fudge instead. Or surprise gift your friends for the holidays with a little Key Lime Fudge!

Key Lime Fudge
This Key Lime Fudge recipe is the perfect blend of sweet and sour!
- 5 ounce can 2% evaporated milk
- 1 2/3 cups granulated white sugar
- 1/2 teaspoon salt
- 12 large marshmallows
- 2 cups white chocolate chips
- 1/4 cup grated lime zest (about 5 limes)
- 2 tablespoons key lime juice (5 to 7 limes, juiced)
- Line an 8" x 8" square pan with aluminum foil; grease the foil with butter. It's not a good recipe for a 9-inch square pan as the fudge will be too thin.
- Combine the milk, sugar and salt in a large heavy saucepan over medium heat. Stir and bring to a boil; boil 8 minutes, stirring constantly at a boil (if you have a candy thermometer, you can bring it to the soft-ball-stage, but I didn't use one). Remove the pan from heat. Add the marshmallows, chocolate, zest and juice, and stir until the marshmallows and chocolate are melted and the mixture is smooth. Scrape the fudge into the prepared pan. Tip the pan to make sure the fudge covers the bottom evenly. Cool completely, then cut into 1-inch squares.
*This recipe can be made with regular limes too.
